<<Disclaimer: Verify this information before applying it to your situation.>> Does anyone know the GF status of Cephalexin (generic Keflex). Recently, I took 1000MGs for a dental pre-med, and about 3 hours later I experienced severe vomiting and diarhea. (This is the second time this has happened.) Twice, my pharmacist has called the manufacaturer and been told it is GF. I wonder if perhaps the person he is speaking to is misinformed...or maybe this is not a Celiac reaction that I am having. I am allergic to all forms of penicillin, so I begin to be limited in my choice of antibiotics. Does anyone know which ones are definitely GF? Thanks for your help!
